Specification of Letters Patent.

-2 8 193.4. Serial No. 874,417.

To all whom it may concern Be it known that I, Greener; M. PAGE, a citizen of'the United States of America, and a resident of Haydenville, in the county of Hampshire and State of Massachusetts, have invented a new and useful Drinking-Fountain Nozzle, of which the following is a specification.

My invention relates to improvements in nozzles for drinking fountains, and consists of :a peculiarly chambered and perforated device that is capable of being mounted. over the open or discharge end of a supply pipe, all. as hereinafter set forth.

The objects of my invention are, first, to produce a device of the kind specified above which is very simple in construction and operation, can be readily applied toalmost .any supply pipe, consisting as it does of practically a single element, is comparatively inexpensive to manufacture, and is quite safe tor use for young children as well as adults; second, to produce such a device that is capable under normal conditions of delivering water in bubbles which are projected well above the place of exit, as is best for drinking purposes, while being incapable even under abnormal conditions of squirting, and which is entirely sanitary; third, to produce a drinking-fountain nozzle so constructed that the water passing through the same is aerated and thus purified, made more lively, and caused to sparkle, and, fourth, to produce a nozzle which in itself is a drinlring fountain.

Other objects will appear in the course of the following description. 7

I attain these objects by the means illustrated in the accompanying drawings, in which Figure 1 is a top planof a practical and that terminates on the inside at the top in a dome 2 having one or more perforations in the sides thereof, that is, lateral per-forations; an intermediate chamber 4 into which said dome extends and opens through said perforations, the walls of such chamber rising first from said stem and then being caused to converge to form a top opening 5, and such walls having one or more perforations 6 therein, which may vbe located :at or near the bottom of said chamber in such a manner that they open outside of said stem, as shown in Fig. 3 and an upper chamber 7 formed by the outer walls of the shell and surrounding the upper part of the walls of said chamber 4:, there being one or more openings 8 in the bot-tom of said chamber 7 which overhangs the parts below, one or more openings 9 in the top ofsaid lastanentioned chamber, and a central opening l0 in said top just above the horizontal plane of the opening 5 or of the upper end of the walls of the chamber l. The opening 10 is of larger diameter than the opening 5. per portion of the walls of the chamber 4 forms what may be termed an interior or inferior nozzle or a throat piece 11. That part of the shell of the nozzle in which the chamher 7 is located may be termed a head 13, and this head has a concave top or mouthpiece let in which are the openings .9 and 1 0.

An annular channel 15 is formed in the overhanging bottom part of the head 18 and the openings 8 lead from such channel inpwardly to the chamber 52.

When water under pressure enters the dome 2, through the stem 1, it inges against the closed top of said dome and is forced out through the perforations 3 into the chamber 1, and then passes upward around the outside of said dome, is constricted by the throat piece 11 or the walls of said chamber, and finally escapes through the openings 5 and 1 0. Thus the column of water is greatly constricted and broken up at the start, then permitted more freedom upon its escape from the dome 2 into the chamber 4, and lastly is again constricted, although less than the first time and without being broken into spray or small streams. The water rises from the opening 10 ready fonds-inking, being presented in the anost palatable as well as most convenient form. Under proper conditions the stream :or coltosquirt, by partially covering the opening '5, such attempt will fail, because the water 7 thus obstructed and that would naturally esof fact, comparatively little water passes into the chamber 7 The exterior overhang of the parts which form the channel 15, such overhang being represented at 16, affords a watershed or guide for the overflow or waste water, which is thereby kept away from the openings 8 and permitted to flow off freely. 7

If an attempt be made to cause the nozzle cape with great force through said opening,

under conditions tending to produce a squirt, instead passes downwardly through the openings 6 and does no harm. The same thing happens in case the opening 5 be closed entirely. Then, again, relief from excessive pressure that might be occasioned by partially or wholly covering the opening 10,

or said opening together with the openings 9, is relieved or prevented by the presence of the openings 8', the water then flowing out at the top of the chamber 1 into the chamber 7'and then passing down and out of said chamber 7 through said openings 8.

Thus it is clear that all possibility of improper use of the nozzle is obviated, and that the latter is especially well'adapted for use by children, since there is no liability that they will get wet by the indulgence of some in the common practice of attempting to squirt the water by covering or constricting the nozzle at the normal point of discharge. lVith most devices of this character it is possible to reduce the stream, by partially closing the exitopening, and to throw or squirt the water with considerable force in various directions, while with my devicethe water, when held back at the nor- I inal point of discharge is relieved of eX- cessive pressure at such point, and being so relieved cannot be manipulated for squirting purposes, but simply finds its escape in other directions and through other exits without material increase in velocity.

' The concave top or mouth -piece 14, with its rounded edges, is quite an important factor in the invention, on account of the bearing surface thus provided and presented for the mouth. This bearing surface is especially well adapted for the reception of the lower front portion of the face, while a person is in the actof drinking, and with it there is no liability of such person being injured by contacting therewith. The upper jaw just under the nose and the chin are the parts of the face that can contact at all forcibly with the top or mouth-piece 1 1-, so that the lips are left free for drinking, and there is little or no danger of injury to the teeth in the event the head be forcibly thrust against such mouth-piece.

The nozzle is self-draining, that is to say, when the water is shut off the nozzle clears itself, the water in the chamber l escaping through the openings 6 and the waste water through the openings 9, 10, and 8.

In Figs. 2 and 3 the nozzle is represented as mounted on a fragment of a supplv pipe 17, the interior of the stem 1 being screwthreaded for that purpose. The stem might equally well be externally screw-threaded and attached to the inside of the supply pipe.

In most cases means must be provided for cutting down and regulating the normal water pressure in the supply pipe before the water reaches the discharge openings 5 and 10, for reasons which will be well understood, and one such means I have shown in Fig. 3, but I am aware that there are many other devices which would serve the same purpose. The regulator in this case is really a reducer, that is to say, it is a device for cutting down the volume, so that, although the velocity is thereby initially increased, such velocity is subsequently reduced to the amount necessary as the water flows through the nozzle, owing, of course, to the reduction in volume. The reducer above referred to consists merely of a tapering seat 18 in the upper terminal portion of the supply pipe 17, and a regulating screw 19, with which latter may be used a check-screw 20. The screw 19 is tapered at the base to correspoml with the taper of the seat 18, and the checkscrew 20 by preference also has a tapered base. Both screws have grooves or water ways 21 in their sides. The interior of the pipe .17 above the seat 18 is screw-threaded to receive the two screws.

In practice, while the check-screw 20 is out of the pipe 17, the regulating screw 19 is turned up or down to produce the right amount of space between the seat 18 and the base of said regulating screw, and then said check-screw is replaced in said pipe and turned down tightly on the head of said screw '19 to prevent the latter screw from or intend to be restricted to any particular means for controlling the volume of Water admitted to my nozzle. It is to be observed, furthermore, that more or less change in the shape and size of said nozzle, and in the arrangement, size and proportions of the perforations and openings therein, may be made without departing from the nature of my invention. In connection with the above reservation attention is called to Figs. 5 and 6. In the first of these two views the openings (5 are omitted from the bottom of the chamber 4, and the Walls of said chamber have lateral perforations or openings 12 therein: while in the last view both sets of openings 6 and 12 are present.

No means is shown for letting on and shutting off the water, in connection with this nozzle, since it is obvious that a suitable valve for this purpose must be provided at some convenient point. It is immaterial whether the water runs constantly through the nozzle, or be admitted thereto intermittently and only as desired for immediate.

use. It may be observed, however, that the nozzle is particularly well adapted for use in cases Where the water is left running, because, owing to its peculiar construction, satisfactory service is rendered by said nozzle when a comparatively small quantity of water is supplied thereto; thus the waste of water when allowed to flow continuously is kept down to the minimum.
